Methods of Documentation VI: Case Management Model

633
The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...

Documentation of Nursing Diagnosis

1.3K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

Combination Therapies and Personalized Medicine

5.1K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Classification of Illness01:17

Classification of Illness

8.0K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Genome-wide Association Studies-GWAS

14.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

科学领域:

  • 医疗信息学 医疗信息学
  • 医疗保健中的人工智能
  • 罕见疾病的诊断 罕见疾病的诊断

背景情况:

  • 由于罕见疾病的流行率较低和呈现方式多样化,它们带来了重大诊断挑战.
  • 有效的诊断工具对于及时干预和改善罕见疾病病例患者的治疗结果至关重要.
  • 基于案例的推理 (CBR) 提供了一个潜在的框架,可以利用患者历史数据来帮助诊断复杂的疾病.

研究的目的:

  • 评估基于案例的推理 (CBR) 在增强罕见疾病的诊断过程中的有效性.
  • 在CBR系统中对患者记录进行不同数据表示方法 (TF,TF-IDF,TF-IDF与语义嵌入) 的比较.
  • 评估ICD-10代码细粒度对诊断预测准确性的影响.

主要方法:

  • 使用了来自法兰克福大学医院的4295例患者病例的数据集,数据使用OMOP常用数据模型进行了标准化.
  • 三种文本表示方法 (TF,TF-IDF,TF-IDF与语义向量嵌入) 应用于患者记录进行相似性搜索.
  • 通过交叉验证,专家对概念相关性的评价以及对ICD-10代码细粒度效应的分析来评估诊断精度.

主要成果:

  • TF-IDF方法实现了高诊断精度,在10个最相似的病例中,平均积极预测值为91%.
  • 在评估的数据表示方法之间没有观察到统计学上显著的差异.
  • 专家评估表明,高权重概念具有中度的医疗相关性,而增加的ICD-10代码细分度导致预测精度下降.
